Abstract: A method for encoding or decoding at least one image, an image being split into blocks of elements. The method includes, for at least one block: splitting the block into at least two areas; and processing at least one of the areas. The processing includes scanning the elements of the area according to a predetermined scanning order, and for at least one scanned element, called a current element: selecting at least one predictor element previously encoded or decoded according to a prediction function; and predicting the current element: from the at least one predictor element, if the at least one predictor element belongs to the area; or from at least one replacement value, otherwise.

Abstract: Proposed is a method for encoding an image of a video sequence, the image including at least two components, including a component representative of the luminance and a component representative of the chrominance, each component being partitioned into blocks, wherein the method involves encoding at least one block of the chrominance component using a BDPCM mode.

Abstract: A method for decoding at least one encoded image within an encoded data stream, the image being split into blocks of elements. The decoding method includes: obtaining from the stream a piece of information representative of a so-called prediction function, the prediction function belonging to a predetermined list of prediction functions; and decoding at least one element of a block of elements, using a differential pulse-code modulation, from an already processed neighbouring element and using the prediction function.
